Aircraft electrical systems depend on reliable connection methods to support communication and power distribution between a wide variety of installed components. One solution used for this purpose is the discrete wire connector assembly, which is built to terminate and organize individual conductors within a controlled interface. With this in mind, this blog will examine core components that make up a discrete wire housing connector and outline key specifications that are typically evaluated when determining their suitability for specific applications.

Whether you are looking to source Ark Technology parts alone or have more varied project needs, any fulfillment process can be difficult when procurement teams are working with limited part data, partial specifications, or only a manufacturer’s name. Gaps like these are undesirable for their ability to slow part identification, create uncertainty around availability, and delay the quoting process, even when partnering with industry experts who know the ins and outs of addressing needs. Therefore, a more structured workflow for carrying out searches and submitting fulfillment requests becomes important for reducing common points of friction. Here on RFQ Experts, we support our customer base in such endeavors by allowing users to locate Ark Technology parts, research and compare options, and submit quote requests with ease through a single platform.

Bearings are used across aircraft systems to support controlled motion and manage load transfer within assemblies that operate under demanding mechanical and environmental conditions. Among the bearing categories used in these applications, components classified under Federal Supply Classification (FSC) 3120 are commonly selected where characteristics like sliding contact, durability, and simplified design are desired. In this blog, we will explore what products fall under FSC 3120, examine where plain bearings are used in aircraft systems, and outline why many procurement teams rely on FSC data for accurate sourcing.

What Is FSC 3120?

Beginning with a National Stock Number (NSN), an NSN is a 13-digit identifier used to standardize how items are cataloged, identified, and managed across defense and federal supply systems. Within this structure, the FSC comprises the first four digits of the NSN and groups products into broad categories based on shared physical and functional characteristics. Under this classification framework, FSC 3120 designates plain, unmounted bearings, covering components that are defined by their use in sliding contact applications without integrated mounting features.

Abrasive disks and stones are commonly used across diverse industries where surface finishing, cutting, and grinding processes must be conducted with exceptional accuracy. Put simply, these tools are designed to shape, smooth, or remove material from workpieces, making them useful for a number of operations. To help those who are currently searching the market for reliable options, this blog will explore various types of abrasive disks and stones, their composition, and the key considerations for selecting the right tool for specific applications.

Common Types of Abrasive Disks

Grinding Disks

Grinding disks are abrasive wheels that can be used to hone rough surfaces or cut through tough materials. These disks are typically made from hard materials like aluminum oxide, silicon carbide, or zirconia to enhance durability by resisting wear.

The role of cabin crews extends far beyond routine service, involving a range of potential emergencies that must be kept in mind and must be managed with calm precision when they occur. Integral to executing every safety protocol efficiently is the safety equipment. In this blog, we will explore some of the different types of aircraft safety equipment available, the scenarios in which they are used, and the rigorous training that cabin crew members undergo to handle emergency situations effectively with these tools.

Actuators are crucial components in modern machinery and technology, as they convert energy into motion and enable precise control over systems. They are found in a wide range of applications, from simple household gadgets to complex industrial machinery. This blog will discuss various types of actuators and their specific applications to provide insight into their significant role in improving efficiency across diverse industries.

Maintaining an aircraft is a highly regulated and complex process that is crucial to its safety and reliability. To avoid any potential issues or mishaps, aircraft maintenance steps are designed for a myriad of aircraft to ensure that their components, systems, and structure are all in optimal condition. In this blog, we will discuss four crucial aircraft maintenance steps that you should never skip to ensure safety, these being inspecting aircraft magnetos, checking aircraft fuel pumps, examining aircraft propellers, and performing routine inspections.

Swaging tools are indispensable devices in the world of manufacturing and aviation, playing a crucial role in shaping and connecting various types of metals and materials. Whether you are a seasoned professional or just starting to explore the fundamentals of metalworking, understanding what swaging tools are and their diverse applications can be incredibly valuable when planning your next project. As such, read on as we discuss them in more detail.

When it comes to the intricate world of computer hardware, one component stands out as the fundamental backbone of any system—the motherboard. Often referred to as the logic board, the motherboard serves as a vital hub, connecting various hardware components and facilitating their seamless communication. In this blog post, we will delve into the fascinating realm of motherboards, discussing their functions and exploring the different types that exist in the industry.

While we may only think of plungers when we actually need them (i.e., when we clog our toilets), plungers are not confined to bathroom settings. In fact, plungers are also commonly employed for workpiece positioning applications. Typically, these types of plungers consist of a rod-shaped body that may or may not feature external threading, and they lock and position parts in place. Unlike toilet bowl plungers, the plungers we will discuss in this blog are of a different variety.
